LOCK.

Application filed August 13, 1906.

Connecticut, have invented new and useful.

Improvements in Locks, of which the following is a full, clear, andexact description,

when taken in connection with the accompanying drawings.

This invention relates to locks, and more particularly to the connectionbetween a socalled cylinder or Yale lock, and the latch bolt of theordinary lock.-

The object of the invention is the production of a lock in which thelatch bolt may be locked in its protracted position from one side of thelock against operation by means of one key in the cylinder or Yale lockon the other side of the lock, and may also be retracted. by anemergency or special key in the cylinder lock. To this end, the cylinderlock is provided with a hub or barrel and surrounding sleeve soconstructed that the hub may be rotated separately by one key and withthe sleeve by another key, and the invention consists of the provisionof a locking device for preventing the retraction of the latch bolt whenthe hub of the cylinder lock is rotated separately, and the provision ofmeans capable of being operated by the sleeve of the cylinder lock forreleasing said locking device, so that the latch bolt may be retractedby means of the hub, together with such other improvements andcombinations of parts, as are set forth and claimed hereinafter.

Referring to the drawings, Figure 1 represents a side elevation of alock embodying the invention, showing the outside escutcheon plate, Fig.2, a front elevation of said lock, Fig. 3, an inside view of the innerescutcheon plate, containing the principal operating parts (the latchbolt being shown retracted), Fig. 1, a similar view, with the latch boltshown protracted, and the locking mechanism for checking the retractionof the latch bolt shown in operative position, Figs. 5, 6 and 7, similarviews of the upper end of the lock, with one of the retaining platesremoved, the parts being shown in various po sitions, Figs. 8 and 9,detailed side and plan views, respectively, of the releasing device,

In all figures, similar letters of reference represent like parts.

As shown in the drawings, the parts designated by the letter A representthe escutoheon plate on the outside of the door, and B the outside knob.

C designates the escutcheon plate on the inside of the door, and D theinside knob. The knobs are mounted on a spindle E in any well knownmanner, and the two escutcheon plates A and C are placed in properalinement with each other by means of telescoping parts F and G, and aresecured by a screw or screws H projecting from the inside escutcheonplate 0 and engaging the part G on the outer escutcheon plate A.

In the face plate I of the lock is pivoted the latch bolt J, which isretracted by means of a sliding plate K in the escutcheon C, to which ispivotally connected a latch lever L, by means of the stud M. The latchoperating lever L is pivoted at N to the escutcheon, and is adapted tobe engaged by the wings O of a hub P rigidly secured to the spindle E,so that the turning of the spindle E will swing the latch lever L on its'pivot and retract the latch bolt J, by means of the plate K (Fig. 3). Aspring Q tends to hold the latch lever L, sliding plate K and latch boltJ- in their protracted positions, shown in Fig. 4.

A cylinder lock R is mounted on the outer escutcheon plate A, and isprovided with a sleeve S loosely mounted therein, having an eccentricbore for a barrel or hub T. Within the cylinder R, sleeve S, and hub Tare suitable tumbler mechanisms for permitting the rotation of the hubor barrel T alone, as in dicated in Fig. 11, or the barrel or hub T andsleeve S conjointly, as indicated in Fig. 12. As this construction issubstantially the same, as shown in a former application made by me forLetters Patent of the United States, filed July 21st, 1905, Serial No.270,691, a detailed description is herein omitted.

The insertion of the key U in the slot V in the barrel or hub T placesthe tumblers in such position, as shown in Fig. 11, that the turning ofthe key U will rotate the hub or barrel T alone, while the insertion ofthe key W places the tumblers in such position, as shown in Fig. 12,that the turning of the key W will rotate the hub or barrel T and sleeveS conjointly. On the inner end. of the bar rel T is secured a spindle X,so that it will rotate therewith.

The inner end of the barrel T is provided with two parallel projectionsT which are slightly cut away as shown at V (Figs. 17 and 18), sothat'there is a slight slackway-for the flattened end X of the spindleX. As shown in Figs. 17 and 18, the barrel is capable of a limitedrotary movement without rotating the spindle X, while continued rotationof the barrel T carries the spindle X with it.

On the inner end of the sleeve S is rigidly secured a plate Y, carryingtwo posts Z on either side of the spindle X. The plate Y is providedwith a perforation A, through which spindle X may project, and in whichit is free to rotate. By this means, when the barrel T is rotated alone,the spindle X is rotated on its axis, as shown more particularly in Fig.14, but when the barrel T and sleeve S are rotated together, the posts Zare turned on the axis of the sleeve S and the spindle X is turned also,as shown more particularly in Fig. 15.

Mounted on the inner escutcheon C is a latch operating block B, which isprovided with an axial perforation 0 correspondin to the transversesection of the spindle X, lout shown slightly wider than the spindle Xin order that the spindle may be capable of a limited lateral play inthe perforation C. The latch operating block B is provided with a bit D,adapted upon the rotation of the block B to engage the extreme end E ofthe latch operating lever L, as shown more particularly in Figs. 4, 5,6, and 7, so that the retation of the latch operating block B by thespindle X of the cylinder lock will swing the latch operating lever onits pivot to retract the latch bolt J. Asliding catch F on theescutcheon C is adapted when in the position shown in Figs. 4 and 6, toprevent the rotation of the latch operating block B by engaging with adepending arm G the straight edge H of the block B. When the slidingcatch F is in the position, however, shown in Figs. 3, 5 and 7, theblock B is free to .turn on its pivot. The catch F is operated. by meansof a lever I, mounted on a shaft K, and having at its free end a slot Ladaptedto receive a stud M on the catch F. The shaft K projects throughthe escutcheon C, and is provided with a thumb piece N on the outside ofthe escutcheon, so that by turning the thumbpiece N the block B may belocked or re leased, and the spindle X correspondingly prevented fromretracting the latch bolt or permitted to retract it. Mounted on theblock B is a cvlindrical piece 0, having a longitudinal sldt P, adaptedto receive the posts Z secured to the sleeve S of the cylinder lock R.The piece 0 is provided with a laterally projecting dog Q, which uponthe rotation of the piece 0 is adapted to engage the depending arm G ofthe sliding catch F, and force it away from the straight edge H of theblock B. (See Figs. 6 and 7.) A plate R secured to the escutcheon C byscrews S, or other suitable means, holds the sliding catch F, the blockB, and the cylindrical piece O in place.

The operation of the lock is as follows:

The latch bolt J may be retracted by the hub O of the spindle E, asabove set forth. When it is desired to lock the latch bolt againstretraction by the key of the cylinder lock, the thumb-piece N is turnedso that the sliding catch F is brought into the position shown in Figs.4 and 6, wherein as above described the depending arm G of the catch Fprevents the rotation of the latch operating block B by means of thespindle X. Consequently, when a key, such as U, is inserted whichrotates merely the hub or barrel T of the cylinder lock, the latch boltcannot be retracted until the sliding catch F is released fromengagement with the block B. This release may be accomplished from theinside of the door by turning the thumb-piece N. When the catch F is inits operative position, the latch bolt can only be retracted from thecylinder lock by the insertion of a key, such as TV, which is adapted torotate the sleeve S with the hub or barrel T of the cylinder lock,because when the sleeve S is rotated, the posts Z are turned on the axisof the sleeve S to the position shown in Fig. 15, and they in turn willturn the cylindrical piece 0 to the position shown in Fig. 7, whereinthe dog Q will engage the depending arm G of the sliding catch F andforce the catch F away from the block B. During the movement of thebarrel and sleeve, the spindle X is not retated, because of the limitedslack-way in the connection between the barrel T and spindle X, so thatthe sleeve is rotated sufliciently to move the sliding catchF away fromthe block B, before tke spindle X is rotated. by the further rotation ofthe barrel T to turn the block B to operate the latch operating lever L,as shown more particularly in Fig. 7.

By this construction, one key or set of keys may be provided for thecylinder lock against which the occupant of the room or house may lockthe latch bolt, while another key may be provided, which, in case ofemergency, may operate the latch bolt even when the sliding catch F hasbeen moved from the inside of the lock to its locked or operativeposition.
